Three optically active Schiff-base ligands have been prepared by condensation of 2-hydroxyacetophenone with (1R,2R)-(-)-1,2-diaminocyclohexane, (1S,2S)-(-)-1,2-diphenylethylenediamine or R-(+)-2,2Ã¢Â€Â™-diamino-1,1Ã¢Â€Â™-binaphthalene, respectively. The products have been characterized by their IR, 1H- and 13C-NMR spectra.
